HomeCultureAir-Ink creates high quality ink from car exhausts! This is Air-Ink. It was produced by connecting an ‘exhaust catcher’ (looks like a large ice tea can) called a “Kaalink” to a car. Then as the vehicle drives around, the soot from the exhaust is collected. From there it can be refined into a high quality ink for pens, brushes, and markers. It was invented in a place called Graviky Labs, which is part of MIT. It is still in its prototype stage, but this video should answer most of your questions. Otherwise you can check out their webpage here: graviky.com/kaalink . The next device they are working on will turn farts into rainbow Trix scented methane.
